A common problem, especially with neuro muscular disorders is the lack of strength to push buttons. I’ve tested some and found that even Xbox buttons (roughly 60grams of pressure required) can be too much sometimes.
Here’s a solution made by Electricreations that creates a touch controller for classic consoles.
This is maybe a complicated but effective solution. The video may be a bit long, but if you have the ability to recreate, could be very useful.
